can anyone help with wiring connections

Being a deaf old git (not totally but my hearing is not as good as I would like), I want to add a pair of apmlified speakers to the PDA so I can hear the voices in my Tom Tom on the Apline clearer since the socket is a 2.5 stero type plug does anyone know which is which on the connections please?

I presume your referring to the Garmin 2.5mm to 3.5mm Jack Adaptor?
nice but not what I was really after
I have found a small set of speakers with a 3.5 jack on the end all that concerns me is the standard headset that comes with the IIi is headset and mic I presumed that a common return (usually the last outer connection and I imagine one of the terminals is for sound and one for mic if so it means only mono sound which is different to what I have been lead to believe just need to know which is the sound out connections on the plug so I can buy a 2.5 plug and wire them up.
The other thing I suppose is I could get a bluetooth headset if the sound from the Tom Tom comes over that but that is a unknown also

i was not talking about the post i made in that thread but more about the DIY stuff people were doing
more about the connector wiring here
http://wiki.xda-developers.com/index.php?pagename=Connectors

that would have been exactly what I wanted only thing it wasn't for the Apline unfortunately

Audio connections on himilaya and alpine are identical.

then one of us is wrong as the connections shown are on a FOUR pin connector my Alpine has a working THREE pin connector

not sure about alpine but i had no probs using my old wallaby headset and cradle on alpines sibling called himalaya

Well I seem to be a blind old git because I just noticed there is a inset on the plug and it is a four connection job sorry guys I only recently got given this thing and a quick glace it looks like three connections but one is inset behind the shield

The 2.5mm connector on BOTH Alpine & Himalaya can accomodate either a stereo or a 4-pin 2.5mm connector.
If the PDA detects a 4-pin plug inserted, it assumes the standard wired earphones and mic are connected, and bypasses the internal mic and routes stereo audio to the earphones.
When a normally-wired 2.5mm stereo plug (or adapter to 3.5mm socket) is connected to the PDA, it just outputs stereo audio.
I use a small 2.5mm stereo plug to 3.5mm socket adapter (having shaved away some plastic to enable it to fit, the socket is inset slightly) - to connect up a standard set of ipod-type speakers to the PDA, and it works a treat.
In short, either obtain a small adaptor to standard 3.5mm socket adaptor or if you get a 2.5mm stereo plug that fits nicely (Maplins, Radio Spares etc) and you want to solder it up yourself, it follows the same wiring cnventions as it's bigger 3.5mm brother, so a wiring diagram is just a google away.

mini USB pinouts and car audio connections

Hello,
I have recently bought a TY TN II and I would like it to play music into my car stereo audio input. Simpler said then done, I have quickly found out!!
I am trying to connect the Kaiser to the car charger and a 3.5 mm head phone jack that I would connect to the car stereo input.
Unfortunately all the Y splitter cable I have seen are very short and would result in having a mess of cable dangling from the Kaiser mounted on the air vent. I would like to just have one cable go into the dash and there connect to the Y splitter and then charger and audio. The goal is to charge and at the same time play music.
I would then need an extension cord to put between the y splitter and the kasier. Here come the problems:
1- How many pins are on the mini usb female that is on the kaiser. Is it a simple 5 pin Mini type A? or is it an 11 pins as some Y cable imply?
2- I could only find one supplier for the mini extension http://www.pc-mobile.net/gugf.htm item CMUE and I am not sure if it is a 5 or 4 wire extension (mini USB can be both I believe). For some reason nobody make this extension???!!!
3- If that extension does not work I could try to make one. What are the pinouts on the Kaiser? I could try to cannibalizing a sycro cable mini male end and find a circuitboard female to connect to the y splitter.
Any help is appreciated. I am getting quite aggravated with this connection problems.
Cheers
Giovanni

Spend a tenner for this
I just ordered it yesterday

Best way would be to buy a BT capable HiFi as with the latest BT fix it will be OK.
BUT!!
If you want a quick hack for BT stereo/handsfree to your car audio.
Buy an iTech clip (it has a 3.5mm jack for audio out) and a car charger for it and a dual cig lighter adaptor.
Fit the iTech clip on you sunvisor (mic is there for phone!) and route its charger cable to the cigarette lighter and the audio cable to your stereo (if you don't have audio in, use a cassette adaptor).
You now can use the clip as Wireless stereo AND it will answer call for you and mute the music and only your power cable to your phone!!!
My iTech clip works seamlessly with the 'Kaiser', not ticks and good audio quality.

This is exactly what I use. I have it connected to an MP3 cable for my stereo and it wprks great!
I have my bluetooth earpiece in to receive calls and the stereo mutes when someone calls.
Also with MS Voice Commander I can also select artists, albums, tracks, or even genre just by pressing the button on my earpiece and speaking!
Its wicked!

I don't want to change the car stereo and I want to just have one simple cable to plug in the Kaiser. The rest should be in the car dashboard and out of sight.
I have bought a Scosche BT receiver but did not work with the Kaiser. BT is kind of miss and hit still. Since I need to connect one cable (power in) anyway I may as well have the audio hard wired.

Does this adapter exist?

I already have a 2.5mm -> 3.5mm stereo adapter to connect my Mogul to my car stereo.
I want a 2.5mm (M) -> Splits two ways:
a) 3.5mm (F) stereo
b) 3.5mm (F) mic
If there isn't one commercially available, I should be able to make it. Any idea what the proper pinout is? And how do we get all signals down 3 wires? (Left+Right+Mic+Gnd+control button)

Any update on finding out how to conect a external speaker and mic to the 6800? I would like to have this type of setup in my car.

You can do a direct splice of the cables coming out if you want, but that requires a little bit on knowledge and a little bit of testing. Basically, you'd take the stock headset and cut off the earbuds and mic. You'd then splice the headphone fead and the mic feed into other lines that would run to your external speaker and mic. Other than that, I don't know of any attachments that do it. You could swing by radio shack and ask them.

I am also interested in doing this. My car has an aux input to the stereo and I would like to install some kind of mic setup so I can use it as a handsfree device. Bluetooth is way too unpredictable so I plan on doing it wired.
You will need a 4-conductor 2.5mm plug along with the Y-cable that came with the phone that has usb and 2.5mm jack.

anyone looking for this setup.. i have a cable i bought off ebay that has a miniusb,which allows you to have a charger plugged in, built in microphone and answer button, and a 3.5mm headphone jack, it works great in the car for hands free (car deck has aux in) , and also works great with my cigarette lighter fm transmitter. anyone looking for this , just type in m

I think i found a solution. I just bought an adapter like this one:

Use topaz as bluetooth headset / use on-board mic

I have searched everywhere and can't seem to find a answer to this...
I use a phone cradle in the car, using my topaz as my music player, connecting my phone to my car stereo with a male-male 3.5mm audio jack.
I want to be able to steam music via bluetooth from any other compatible phone / device to my phone, meaning I don't have to trail cables everywhere when a passenger wants to play something.
I would have thought this to be a simple-ish thing to setup but cannot find any information on how to do it. Is it even possible, and where would I start if it is?
I also want to use my on-board mic when the headset is plugged so I can have call audio over car speakers, although iv been led to believe this isn't possible because of hardware reasons, can anybody clarify that?
Apologies if this is in the wrong forum, not really sure where it should have gone.

If I understand you correctly, you want to stream music TO your phone over BT from another device? Not possible.
For hearing call over speakers and using mic, you need to get the M-F w/built in mic.

I too don't think it will be possible to stream music from another device to your phone except if you transfer the entire music mp3 file via bluetooth to your device and then play it from there.
Regarding the possibility of using the device's microphone whilst using the car speakers for sound, again I'm afraid I don't think this is possible. I have a similar set-up to you in that my TD2 is connected to an FM transmitter which also charges my TD2 at the same time in a nice cradle. The TD2 thinks it is connected to a headset when cradled. The microphone is inactive in this state which is a shame as it would have made a good hands free system if it were to be active....

I use this set up as well. You just need the cable with the built in mic.
My RF Transmitter has a male plug, So I found the HTC cable that has the HTC USB to Female with built in mic. This is my basic set up.

That set up looks great Bruce, but I don't want to be fiddling about plugging in so many cables with so many wires visible. Brodit does something similar too, all in a cradle with an extended wire so you would be able to hide all the cables....

[Q] Using as Car Head Unit (no 3.5mm jack)

Ok so Ive been looking in to building a Android tablet in to my car to use as a head unit.
Basically im running amps in my car so i need an audio signal from the unit.
I DONT want to simply run the 3.5mm headphone jack cable to the amps cause it will sound shocking.
I was just wondering if there are other ways of doing it.
I was looking in to something like sending the audio out the usb.
But what interested me was using using the OEM desktop dock with HDMI and using the HDMI audio out and using a DAC (digital audio converter i think) and converting the signal to analogue.
Does anyone know if this is possible at all or if there are better ways of doing it?
Ive been spending hours trying to find out a way of doing this!

I'm working on this same project. I bought the dock connector to get access to charging and a line out simultaneously. The regular RCA adapter doesn't give you the ability to charge. I'm thinking the amps will be fine with the line output.
